I really feel this may be that they are going to phase out the contender
The Original Contender is long out of production.
I've owned all three and just got rid of my last original Contender frame. I much prefer the G2 as a pistol. In the winter the old Contender's trigger was just too light for woods walkin IMO. I just didn't feel safe with a 1-1/2 pound trigger and numb, gloved fingers.
I don't think you'll notice an ounce or two of extra weight.
FWIW, my .22 WMR G2 is my best offhand shooter I've ever owned. I don't do a lot of missin' with that combo!
Your FFL will verify what he is selling you (pistol or carbine). If it's a private sale, maybe call T/C.
